Effect of anisotropic transmission of a photon pulse to an electronic system in a nanotube with a spiral defect under conditions of an external magnetic field

The authors theoretically investigate the specifics of photon-drag effect in a nanotube with spiral defect, that relate to asymmetric electron energy spectrum in a longitudinal field. The researchers have discovered an effect of anisotropic transfer of photon impulse to the electronic system in spectral dependence of photon-drag effect current density. It is shown that in case of a standing electromagnetic wave in the nanotube with spiral defect, the process of impulse transfer from a wave to electrons leads to emergence of a new type of electromotive force.
